Abstract: 1,039,461. Pipe Joints. ROLLS-ROYCE Ltd. Jan. 25, 1963, No. 3323/63. Heading F2G. A flexible coupling for pipes or the like comprises two annular end parts 16, 18, one connected to each end of a pipe 10, 12 or the like, the end parts being interconnected by a universal joint including a gimbal ring 20. The gimbal ring is provided with two sets of pivot members 24a, 24b, each set having two part annular pivots arranged diametrically opposite each other with their longitudinal axes being disposed perpendicular to the longitudinal axes of the other set of members. Each set of pivot members are disposed on opposite sides of the transverse plane of the gimbal ring. In the construction shown the pivot members 24a, 24b co-operate with recesses formed in the end parts 16, 18. The pivots and recesses each subtend an arc of 180 degrees. The gimbal ring 20 is formed by securing to a ring two, diametrically opposed annular members and cutting the ring along its transverse median plane (Fig. 3, not shown). The two end parts are also formed by cutting a machined component along its transverse median plane. The two halves of the gimbal ring are mounted in respective end parts by rotating the halves in the mouth of the end part and thus sliding the pivot members into their recesses. The two halves of the gimbal ring are then welded together, apertures being provided at the abutting edges to facilitate welding. The joint is sealed by a flexible bellows 30 joined at each end as by welding to an end part. A heat shield may be provided within and spaced from the gimbal ring, the shield comprising either a metal sheet attached at its periphery to the gimbal ring or interengaging portions, each portion being affixed to an end piece.

Abstract: 690,105. Soot blowers. GORDON & CO., Ltd., J., and MASHEDER. H. Feb. 5, 1951 [Feb. 9, 1950], No. 3378/50. Class 99 (ii). A nozzle tube 2 is advanced and retracted to and from the operative position by a fluid-pressure-actuated piston 8 which may surround a tubular guide 13 and work in a cylinder 9, under the control of a shuttle valve 26, pilot valves 20, 30 being operated, preferably by pneumatic pressure, in response to movement of the tube to the advanced position to cause opening of a blowing- medium valve 6 and in response to movement of the valve 26 to cause retraction of the tube and closing of the valve 6. The pressure of the blowing medium communicated through a passage 19 may, together with a spring 46, act upon a piston 18 of the valve 6 to hold the valve upon a seat 16, and the valve 20 may be actuated by a piston 21 against the pressure of a spring 22. With the valve 26 in the position shown, pressure fluid passes through ports 27, 32 and port 25 in the cylinder 9 to advance the tube 2, the forward end of the cylinder being exhausted of pressure fluid through ports 24, 33 and 34. When the piston 8 is in the forward position a port 28 is uncovered and pressure fluid passes to the valve 30 and then to the valve 20 which closes the passage 19 and allows the cylinder 14 of the piston 18 to be vented to atmosphere through a port 23 so that the valve 6 is opened by the pressure of the blowing medium. After a predetermined blowing time the valve 26 is shifted, e.g. manually, mechanically, pneumatically or hydraulically, to a position whereby pressure fluid is cut off from the valves 20, 30 so that the valve 6 is closed, and admitted to the port 24 to retract the tube 2. Specification 690,106, is referred to.

Title: Methods of and apparatus for controlling the advancement of materials

Filed: 1970-01-27
Abstract: 1300801 Extruding; drawing WESTERN ELECTRIC CO Inc 27 Jan 1970 [28 Jan 1969 14 Nov 1969] 3860/70 Heading B3P A continuous bar feeding apparatus has one or more fluid flow zones D 1 , D 3 , D 5 , D 7  where the flow is along the surface of the bar R to produce a drag force on the bar to feed it or retard the feed. The fluid flow may be continuous in a forward-reverse pattern or each zone may have a closed fluid-loop with different fluids, Fig. 2 (not shown). The pressure levels of the fluids are controlled by pressure ratio valves (RV) between the zones. The fluids may have different viscosities and treat the bar for cleaning, rinsing, chemical treating and lubricating respectively. One embodiment of feeding apparatus, Fig. 3, for an extrusion die 12 comprises a housing 16 with a set of flow reversal cells 20, 22, 24, 26. The cells each comprise an insert 30, Fig. 4 (not shown), and end plates 36. arranged to provide a forward-reverse flow path. The plates 36 and the end wall of the housing have low-friction inserts (40), 60. For best results it has been found necessary to have the internal diameter of the housing greater than twice the bar diameter. In one example using this apparatus the fluid is polyethylene micropowder and silicone fluid. The lengths of the flow path along the bar may vary from zone to zone, Fig. 7 (not shown). The fluid may be cooled. In a second embodiment, Fig. 8, the bar R is fed to a high pressure extrusion apparatus 200 by a fluid-drag feeder 110 and the extruded product may be controlled by either a fluid-drag feeder 310 to accelerate the feed or a feeder 210 to retard the feed. Alternatively the feeder at the output side may initially retard the extruded wire W and the flow direction is then reversed to accelerate the wire. In some operations the input feeder may be dispensed with and the wire drawn through the die by the output feeder 310. The pumps F/P of the feeders and the extrusion apparatus 200 are controlled by adjustable pressure control valves, Fig. 9 (not shown). The feeders may include electric heating elements 70, Fig. 11, so that the viscosity of the fluid can be varied. The elements of the units are connected in series and the current controlled by an amplifier fed with signals from transducers for the extrusion forces. The apparatus is particularly suited for extruding and drawing brittle metals such as bismuth and beryllium but can be used for aluminium.

Title: Improvements in and relating to sheets for writing, printing, tracing and the like
IPC: C08J7/12
Filed: 1935-02-06
Abstract: Cellulose ester sheets are superficially saponified on one or both faces and are subjected to a de-polishing treatment in order that they may be capable of carrying impressions, writings, designs, and tracings.  The cellulose ester may be cellulose acetate.  The sheet may be made up of more than one cellulose ester or of any cellulose derivative provided that it has a surface layer of cellulose ester. The saponifying agent may be caustic alkali, ammonia, or an amine. For depolishing the sheet, a swelling agent such as ethyl alcohol or a mixture of alcohol and acetone is applied to the sheet which may then be pressed into contact with a roughened cylinder.  The cylinder may be heated. The swelling agent may be applied by a roller or by a bath treatment.  The saponification and depolishing treatments may be combined by using an alcoholic solution of caustic alkali while the sheet is in contact with the roughened roller.  The sheet is subsequently washed by sprays of warm water and then dried.  Resin or wax may be added to the saponifying liquid to avoid any tendency of ink to smudge when applied to the finished sheet.  The saponification or depolishing may be confined to selected areas or may be carried out over the whole surface.
